A new cerium-loaded cation exchange resin adsorbent for arsenite was prepared by impregnating cerium onto cation exchange resin. Batch adsorption experiments under various conditions, such as time, temperature, pH and coexistent ions were carried out to evaluate the adsorption characteristics of Ce-loaded resin in the removal of As(III) from aqueous solutions. The results show that the adsorption...
The adsorption equilibrium of CO2 was measured on coconut shell activated carbon by using a static volumetric method. Adsorption isotherms over the temperature ranged 308 K ~ 353 K were measured. The results showed that the capacities of adsorption of carbon dioxide on activated carbon at different temperatures were as follows: 308 K > 323 K > 338 K > 353 K. The absorption capacity increases...
The kinetics of carbon monoxide and propylene oxidation as well as nitrous oxide reduction on a Pd–Rh catalyst were determined with synthetic gas mixtures between 500 and 700K. The overall reaction rate expression was constructed from elementary reaction steps and the kinetic parameters were determined from the experiments. A transient mathematical model has been developed to simulate automobile exhaust...
